Been here awhile...
I think the "plunger" to the right of the trunk latch loop is nothing more than a spring to push the trunk up about a half inch when the remote trunk opener in the driver side door is actuated. I can't find any wiring that goes to it. The trunk light and the "trunk open" warning light on the dash are tied in with the trunk latch. When I manually closed the latch with my finger, the trunk light and warning light went out. When I press the trunk opener on the trunk lid, the latch opens and the lights come on.
Bob, dond13 - I assume you don't have the remote trunk release on your cars since you don't have the "plunger".
Yes, I have the remote trunk release on mine. That is what I'm guessing the switch on the right side behind the flap is.
